# Calcium chloride dissolves in water to form calcium and chloride ions, producing 83kJ of heat per mole. Calculate final temp. when 0.02 moles of calcium chloride is dissolved into 150ml of water at a temperature initially of 19 degrees?

##### 1 Answer

#### Answer:

#### Explanation:

Given:

The process of dissolving

Compute the heat energy released for

This heat energy must be absorbed by the water. The reference Specific Heat gives us a useful equation:

Substitute

The reference, also, gives us a value for c:

Substitute 150g for m:

Substitute
